A cliff shows many horizontal rock layers.
The bottom layers are dark and tightly packed, while the top layers are lighter and crumbly.
What can you infer about the age and formation of the bottom layers compared to the top layers?
What is the bottom layers are older. Sediment is deposited over time so the lower layers form first and are older.
